The best/worst thing about the Buddha’s message is that he told us, obliquely, that we do this to ourselves.
You, and only you, can choose to start meditating and work your way to nirvana/enlightenment/awakening/the deathless/the end of samsara, pick your term.
Along the way you will inevitably notice your bad mental habits. A lot of them are sort of self liberating in the sense that they stop when you notice them, but some of them you have to choose to give up.
One of the worst in that category is the very human tendency to dream up reasons to worry.
As I type this, people are dreaming up every possible scenario for what could go horribly wrong in the upcoming election, some more plausible than others.
The Dalai Lama admonished us to take action to change bad situations where we could, but not to waste energy worrying about those we have no control over. We have to assume he is not very happy about the Chinese invasion of Tibet, but he still usually looks pretty happy, not because he doesn’t care, but because he knows he can do nothing to eject the Chinese from Tibet, so he doesn’t waste his energy, or make himself miserable, worrying about the situation.
All worrying does is make you miserable. You don’t help anyone else. This is a bad habit you can easily recognize and choose to give up.
So stop looking for reasons to worry.
Please help spread the word.
